In biology, homology is the existence of shared ancestry between a pair of structures, or genes, in different taxa.A common example of homologous structures is the forelimbs of vertebrates, where the wings of bats, the arms of primates, the front flippers of whales and the forelegs of dogs and horses are all derived from the same ancestral tetrapod structure.

Homology (biology)

It is ultimately the HOX protein distribution that dictates the varying body architecture within a wide range of organisms that rely on the hox gene expression.

In Drosophila, there are eight hox genes, which are generally divided up into two complexes, the antennapedia and bithorax. Lamarckism (or Lamarckian inheritance) is the hypothesis that an organism can pass on characteristics that it has acquired through use or disuse during its lifetime to its is also known as the inheritance of acquired characteristics or soft is inaccurately named after the French biologist Jean-Baptiste Lamarck (–), who incorporated the action of soft.
